Hi hshanka,
You can read a little more about the Cool Luxe and my thoughts about it and its “value” in post #9 here.
These would be choices based strictly on personal preferences so of course I can’t offer advice for others on which they may like better. There are a few “needs” connected to pillows but it is more about individual preferences than a mattress because subjective issues play a much larger role. There is more information and feedback and links to resources about pillows in the pillow thread here.
I personally would choose latex (shredded or solid) over memory foam and because of the nature of memory foam I would personally tend towards solid memory foam over shredded but assuming the pillow keeps me in good alignment … the individual “feel” of a pillow and its cover would be more important to me than its specific material (assuming it is a “safe” material) and I am always open to being surprised about what I think about a specific pillow. For me it can even change with my mood or circumstances. I don’t think I have really decided which is the absolute “best” pillow for me (and I certainly couldn’t for others) because my own opinions seem to change back and forth over time but I think I lean more towards shredded latex than solid latex although I have and use both (and other types as well).
You’re very welcome … and thanks for the kind words 
Phoenix
